Javascript, regular expressions

[mike509123]

Hi,
I am looking to create a regular expression that only allows Upper Case and Lower Case Letters and hyphens.

I have the following so far which allows for uppercase and lower case characters. How do I modify it to include "-" also?

var re = new RegExp("^([a-zA-Z])+$");

[a-zA-Z/-]


also a good way to test

j4606, you're close:

[a-zA-Z[!]\[/!]-]

This is good to all consideration.
[tt]var re=new RegExp("^([a-zA-Z[highlight]-[/highlight]])+$");[/tt]
This are unnecessary but eventually fine.
[tt]var re=new RegExp("^([a-zA-Z[highlight]\\-[/highlight]])+$");[/tt]
[tt]var re=/^([a-zA-Z[highlight]\-[/highlight]])+$/;[/tt]
This is deficient but works by fortune that "-" has no need to escape.
[tt]var re=new RegExp("^([a-zA-Z[red]\-[/red]])+$");[/tt]
